Amsterdam IT Consultant's Life Disrupted by AI-Induced Psychosis After ChatGPT Experiment

Dennis Biesma, an IT consultant from Amsterdam, experienced a severe reality loss and psychosis following his experimentation with ChatGPT in late 2024. Initially fascinated by the technology during a period of personal transition, Biesma became convinced he could amass a fortune with the assistance of his AI companion. This psychological episode resulted in significant personal and financial consequences, including the dissolution of his marriage and the loss of 100,000 euros. Experts are now issuing warnings about the potential for such AI interactions to trigger psychotic breaks. Biesma's situation was compounded by feelings of isolation following shifts to remote work post-pandemic and his wife's absence from the home. His adult daughter had also moved out, and he occasionally used cannabis in the evenings, a long-standing habit. The case highlights emerging mental health risks associated with advanced conversational AI.
